                  where such changes and/or additions to the Program originate from
                  and are Distributed by that particular Contributor. A Contribution
                  &ldquo;originates&rdquo; from a Contributor if it was added to the Program by such

                contents of the Program, including, for purposes of clarity any new file
                in Source Code form that contains any contents of the Program. Modified

              <ul>
                <li>a) Subject to the terms of this Agreement, each Contributor hereby
                  grants Recipient a non-exclusive, worldwide, royalty-free copyright
                  license to reproduce, prepare Derivative Works of, publicly display,
                  publicly perform, Distribute and sublicense the Contribution of such
                  Contributor, if any, and such Derivative Works.
                </li>
                <li>b) Subject to the terms of this Agreement, each Contributor hereby
                  grants Recipient a non-exclusive, worldwide, royalty-free patent
                  license under Licensed Patents to make, use, sell, offer to sell,
                  import and otherwise transfer the Contribution of such Contributor,
                  if any, in Source Code or other form. This patent license shall
                  apply to the combination of the Contribution and the Program if,
                  at the time the Contribution is added by the Contributor, such
                  addition of the Contribution causes such combination to be covered
                  by the Licensed Patents. The patent license shall not apply to any
                  other combinations which include the Contribution. No hardware per
                  se is licensed hereunder.
                </li>
                <li>c) Recipient understands that although each Contributor grants the
                  licenses to its Contributions set forth herein, no assurances are
                  provided by any Contributor that the Program does not infringe the
                  patent or other intellectual property rights of any other entity.
                  Each Contributor disclaims any liability to Recipient for claims
                  brought by any other entity based on infringement of intellectual
                  property rights or otherwise. As a condition to exercising the rights
                  and licenses granted hereunder, each Recipient hereby assumes sole
                  responsibility to secure any other intellectual property rights needed,
                  if any. For example, if a third party patent license is required to
                  allow Recipient to Distribute the Program, it is Recipient&#039;s
                  responsibility to acquire that license before distributing the Program.
                </li>
                <li>d) Each Contributor represents that to its knowledge it has sufficient
                  copyright rights in its Contribution, if any, to grant the copyright
                  license set forth in this Agreement.
                </li>
                <li>e) Notwithstanding the terms of any Secondary License, no Contributor
                  makes additional grants to any Recipient (other than those set forth
                  in this Agreement) as a result of such Recipient&#039;s receipt of the
                  Program under the terms of a Secondary License (if permitted under
                  the terms of Section 3).

                  accordance with section 3.2, and the Contributor must accompany
                  the Program with a statement that the Source Code for the Program
                  is available under this Agreement, and informs Recipients how to
                  obtain it in a reasonable manner on or through a medium customarily

                </li>
                <li>
                  b) the Contributor may Distribute the Program under a license
                  different than this Agreement, provided that such license:
                  <ul>
                    <li>i) effectively disclaims on behalf of all other Contributors all
                      warranties and conditions, express and implied, including warranties
                      or conditions of title and non-infringement, and implied warranties
                      or conditions of merchantability and fitness for a particular purpose;
                    </li>
                    <li>ii) effectively excludes on behalf of all other Contributors all
                      liability for damages, including direct, indirect, special, incidental
                      and consequential damages, such as lost profits;
                    </li>
                    <li>iii) does not attempt to limit or alter the recipients&#039; rights in the
                      Source Code under section 3.2; and
                    </li>
                    <li>iv) requires any subsequent distribution of the Program by any party
                      to be under a license that satisfies the requirements of this section 3.
                    </li>
                  </ul>
                </li>
              </ul>
              <p>3.2 When the Program is Distributed as Source Code:</p>
              <ul>
                <li>a) it must be made available under this Agreement, or if the Program (i)
                  is combined with other material in a separate file or files made available
                  under a Secondary License, and (ii) the initial Contributor attached to
                  the Source Code the notice described in Exhibit A of this Agreement,
                  then the Program may be made available under the terms of such
                  Secondary Licenses, and
                </li>
                <li>b) a copy of this Agreement must be included with each copy of the Program.</li>
              </ul>
              <p>3.3 Contributors may not remove or alter any copyright, patent, trademark,
                attribution notices, disclaimers of warranty, or limitations of liability
                (&lsquo;notices&rsquo;) contained within the Program from any copy of the Program which
                they Distribute, provided that Contributors may add their own appropriate
                notices.
              </p>
              <h2 id="commercial-distribution">4. COMMERCIAL DISTRIBUTION</h2>
              <p>Commercial distributors of software may accept certain responsibilities
                with respect to end users, business partners and the like. While this
                license is intended to facilitate the commercial use of the Program, the
                Contributor who includes the Program in a commercial product offering should
                do so in a manner which does not create potential liability for other
                Contributors. Therefore, if a Contributor includes the Program in a
                commercial product offering, such Contributor (&ldquo;Commercial Contributor&rdquo;)
                hereby agrees to defend and indemnify every other Contributor
                (&ldquo;Indemnified Contributor&rdquo;) against any losses, damages and costs
                (collectively &ldquo;Losses&rdquo;) arising from claims, lawsuits and other legal actions
                brought by a third party against the Indemnified Contributor to the extent
                caused by the acts or omissions of such Commercial Contributor in connection
                with its distribution of the Program in a commercial product offering.
                The obligations in this section do not apply to any claims or Losses relating
                to any actual or alleged intellectual property infringement. In order to
                qualify, an Indemnified Contributor must: a) promptly notify the
                Commercial Contributor in writing of such claim, and b) allow the Commercial
                Contributor to control, and cooperate with the Commercial Contributor in,
                the defense and any related settlement negotiations. The Indemnified
                Contributor may participate in any such claim at its own expense.
              </p>
              <p>For example, a Contributor might include the Program
                in a commercial product offering, Product X. That Contributor is then a
                Commercial Contributor. If that Commercial Contributor then makes performance
                claims, or offers warranties related to Product X, those performance claims
                and warranties are such Commercial Contributor&#039;s responsibility alone.
                Under this section, the Commercial Contributor would have to defend claims
                against the other Contributors related to those performance claims and
                warranties, and if a court requires any other Contributor to pay any damages
                as a result, the Commercial Contributor must pay those damages.
              </p>
              <h2 id="warranty">5. NO WARRANTY</h2>
              <p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT PERMITTED
                BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN &ldquo;AS IS&rdquo; BASIS, WITHOUT
                WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING,
                WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT,
                MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is
                solely responsible for determining the appropriateness of using and
                distributing the Program and assumes all risks associated with its
                exercise of rights under this Agreement, including but not limited to the
                risks and costs of program errors, compliance with applicable laws, damage
                to or loss of data, programs or equipment, and unavailability or
                interruption of operations.

              <p>If Recipient institutes patent litigation against any entity (including a
                cross-claim or counterclaim in a lawsuit) alleging that the Program itself
                (excluding combinations of the Program with other software or hardware)
                infringes such Recipient&#039;s patent(s), then such Recipient&#039;s rights granted
                under Section 2(b) shall terminate as of the date such litigation is filed.
              </p>
              <p>All Recipient&#039;s rights under this Agreement shall terminate if it fails to
                comply with any of the material terms or conditions of this Agreement and
                does not cure such failure in a reasonable period of time after becoming
                aware of such noncompliance. If all Recipient&#039;s rights under this Agreement
                terminate, Recipient agrees to cease use and distribution of the Program
                as soon as reasonably practicable. However, Recipient&#039;s obligations under
                this Agreement and any licenses granted by Recipient relating to the
                Program shall continue and survive.
